Rydym yn cyfarfod yma.
Formal: Dewch yma. Dere 'ma.
you can't translate englsish phrases into welsh as you can words... so instead you could say , "byswn i'n dwlu taset ti yma" = i'd love it if you were here
"You are Welsh" = Rwyt ti'n Gymreig
Mae'n hyfryd cael bod yma.
'I am English' in Welsh is 'Dwi yn Saesneg'
You can say "Tud yma, boi!" (tid uh-ma boy) which is what I'd say, or if you wanna use the proper word for "boy" in Welsh then it's "bachgen" but it's less of a mouthful to say "boi", heh.
'Our Friends' in Welsh is 'Ffrindiau Ni' :)
Hello nice to meeting you I am here for interview
To say "your house" in Welsh, you would say "eich tŷ".
Cymraeg
No in Welsh is dim.
"y diwedd" is how you say it in Welsh language.
